Picture of error and how the cf adapter is in the caddy.
Tried swapping cf adapters. It's the same. Also noticed that these adapters cant be on the same channel as master slave.
Kickstart is 3.1, os is 3.9. Drivers from elbox is afaik the latest recommended, but last updated 2006'ish. Trouble is that the error comes before anything is loaded as you can se from the screenshot.
When cf-adapter is connected directly to the controller all is ok.
